SAMD21G18A Development Board

An Open Source SAMD21 Development Board by sirmylesavery @

This project started after my first introduction to PCB design at my 2019 summer internship. At that internship, I designed a board that used a SAMD21 to control a GPS and LoRa module. This was my first introduction to the SAMD21 MCU and I immediately was interested in its capabilities. As a side project to work, I started to design a development board centered around this module.
